Grade 5 Titanium Hex Flange Banjo Bolt - Pre-Drilled Safety Wire Holes by China Suppliers & Factory for Motorcycles
Key Features
Six Pre-Drilled Safety Wire Holes
Each titanium banjo bolt head is pre-drilled with six evenly spaced safety wire holes. When secured with safety wire, it prevents loosening under vibration and meets track-day and professional racing inspection standards.
Precision Polished Oil Passage
The internal oil passage is polished to reduce fluid resistance. This delivers smoother, more linear brake lever feel compared with OEM steel bolts.
Integrated Wide Sealing Flange
The wide flange increases contact with crush washers. It spreads clamping force evenly under high brake pressure, helping prevent leaks during repeated use.
45% Lighter Than Steel Bolts
Manufactured from Ti-6Al-4V, the titanium banjo bolt weighs about 45% less than steel bolts. Reduced unsprung weight improves suspension response and steering agility for performance upgrades.
Engineered for Brake Fluid Environments
Optimized for DOT4 and DOT5.1 fluids, this titanium banjo bolt resists rust, oxidation, and staining. It keeps brake hardware clean and easy to service.
Installation & Maintenance Guidance
Torque Control: Follow the vehicle manufacturer’s torque for the equivalent steel bolt size when installing the Titanium Banjo Bolt. Replace crush washers each time for reliable hydraulic sealing.

Application Scenarios
Motorcycle Performance & Maintenance
● Motorcycle Brake Caliper & Master Cylinder Connections
The titanium banjo bolt is mainly used on M10 brake line fittings linking calipers and master cylinders. Reduced weight at the fork supports quicker suspension response, and the safety wire holes meet track inspection rules.
Hydraulic Clutch Systems
● Hydraulic Clutch Line Assemblies
Installed on M8 or M10 hydraulic clutch connections. It ensures secure clamping and stable sealing through repeated heat cycles for consistent clutch feel.
System Compatibility
● Brembo & Major Brake System Compatibility
Compatible with Brembo calipers and Japanese brake systems like Nissin, Tokico, and Magura. M10 is commonly used on front brakes, while M8 fits compact hydraulic setups.
Frequently Asked Questions (FAQ)
What material is this banjo bolt made of, and what are its benefits?
It is manufactured from Grade 5 Titanium (Ti-6Al-4V). This material provides high tensile strength (≥ 900 MPa) and excellent corrosion resistance while being 45% lighter than standard steel bolts.
Why does the titanium banjo bolt have six pre-drilled holes?
The six pre-drilled holes on the hex head allow safety wire to be easily installed. This prevents the bolt from backing out or loosening due to track-day vibrations and meets safety inspection standards.
What is the recommended installation torque for this titanium bolt?
You should follow the original vehicle manufacturer's torque specifications designated for the equivalent steel bolt size. Remember to use new crush washers during installation to ensure a proper seal.
Are these titanium banjo bolts compatible with Brembo brake systems?
Yes, they are compatible with Brembo calipers as well as other major brake systems like Nissin, Tokico, and Magura. Make sure to choose the correct thread size (M10 or M8) and thread pitch (1.0mm or 1.25mm) for your setup.
Does this bolt resist damage from brake fluid?
Yes. The titanium banjo bolt is engineered specifically for brake fluid environments, offering outstanding resistance to rust, staining, and oxidation when exposed to DOT4 and DOT5.1 fluids.
Can I order custom sizes or finishes?
Yes, OEM customization is supported. You can customize the thread type, head style, finish (Natural Titanium, Anodized, or PVD Coating), and length to fit your specific requirements.
